Food Preservation involves techniques used to extend the shelf life of food, maintaining its quality and safety.

Core Techniques

Canning

  • Sterilize jars
  • Seal airtight
  • Store in cool, dark place
Decision diagram starts with a tested recipe and branches to boiling-water or pressure canning according to the recipe's food and acidity. Low-acid foods require pressure canning; jar size, processing and elevation instructions remain essential.
Canning safety depends on the tested processing method, not just an airtight seal. This conceptual decision guide is a route to the full recipe, not a substitute for processing times, pressure settings or elevation adjustments. Original conceptual diagram based on National Center for Home Food Preservation, University of Georgia, Ensuring Safe Canned Foods.
